3D Tissue Models SynVivo is a physiological, cell-based microfluidic platform that provides a morphologically and physiologically realistic microenvironment allowing real-time study of cellular behavior, drug delivery and drug discovery. SynVivo 3D tissue models recreate complex in vivo microenvironment including scale, morphology, hemodynamics, and cellular interactions with a side-by-side architecture enabling real-time visualization and analysis. The SynVivo 3D tissue models have been extensively validated for oncology, neuroscience, inflammation and toxicology applications. Available models include SynTumor (Cancer), SynBBB (blood brain barrier), SynRAM (Inflammation) and SynTox (Toxicology). Simple, Low Cost Fabrication Tissue Image Digitized Network Microfabricated Chip SynAssay Platform Simple, Robust Protocols Cell Seeding (-5 min) Cell Culture (12-48 hrs) Experiment (hours-weeks) SynVivo microfluidic chip designs are based on actual microvascular network images or an idealized vascular network to support in vivo replication of physiological, morphological and cellular makeup for cell-cell and cell-drug interaction assays. Realistic Microvascular Networks: Replicate in vivo physiological, morphological and cellular makeup for cell-cell and cell-drug interaction across the vasculartissue interface. Idealized Microvascular Network: Replicate in vivo fluidic and cellular makeup for cell-cell and cell-drug interaction across the vascular-tissue interface. Perform morphologically and physiologically realistic assays
SynTumor 3D Cancer Model The SynTumor TM 3D tissue model allows real-time visualization and quantitative assessment of cell-cell and cell-drug interactions in a physiologically realistic tumor microenvironment. The system enables analysis of circulation in the microvasculature, transport across the vessel walls, and drug delivery to tumors. Side by side architecture enables quantitative real-time visualization Physiological leaky vasculature with engineered porous structures Morphologically realistic in vivo based architecture Monitor interactions between tumor, stromal, vascular and immune cells Starting with scans of vascular networks incorporated with interstitial and tissue/tumor spaces, the SynTumor model recreates an in vitro tumor microenvironment akin to a viable histological slice. SynTumor Predicts in Vivo Drug Delivery Responses A 3D cervical cancer model was developed using SynTumor to evaluate gene delivery efficiencies of nanopolymers being evaluated for use in a clinical trial. GFP gene delivery using both direct and vascular injection routes were compared. In contrast to static well plate assays, the SynTumor model was successful in correctly predicting the in vivo responses of the nanopolymers. Both polymers A and B had uniform GFP transfection of the 3D tumors following direct injection similar to in vivo observations. However, following vascular injection only polymer A was able to diffuse across the endothelium and uniformly transfect the 3D tumor replicating the in vivo response. Monitor Phenotypic Behavior of Tumor Cells in Real-Time The microenvironment of two different breast tumors were created using the SynTumor model to evaluate their metastatic potential over a four week period. The highly metastatic tumor cells intravasated the vascular channels and rapidly invaded the adjacent tissue chambers and highlighted spindle morphology, a classical sign of invasive tumor cells. In contrast, the non-metastatic tumor cells grew slowly in clusters indicative of a benign tumor. SynVivo and in vivo response show that both the nanopolymers labeled A and B transfect the core of the tumor with uniform GFP expression following direct injection. In contrast, vascular injection route in SynVivo shows uniform transfection of the tumors only for nanopolymer labeled A matching the results observed in vivo. Metastatic Tumor Non-Metastatic Tumor A metastatic tumor (left image) rapidly spreads to adjacent chambers while a non-metastatic tumor does not. Inset shows stained images highlighting elongated protrusions for metastatic tumor in contrast to non-metastatic tumor. This model can be used to screen tumor cell populations for their metastatic potential. Recreate the tumor microenvironment
SynBBB 3D Blood Brain Barrier Model SynBBB TM recreates the in vivo brain microenvironment by replicating a histological slice of brain tissue cells in communication with endothelial cells across the blood brain barrier (BBB). Interactions between brain tissue cells and endothelial cells are readily visualized in the SynBBB model using biochemical or electrical analysis. SynBBB is the only in vitro BBB model with: Accurate in vivo hemodynamic shear stress Real-time visualization of drug transport, cellular and barrier functionality Compatible with standard analytical instrumentation Robust and easy to use protocols Schematic of the SynBBB Model. Apical chamber (outer channels) are for culture of vascular (endothelial cells) while basolateral chamber (central chamber) are for culture of brain tissue cells (astrocytes, pericytes, neurons). Porous architecture enables communication between the vascular and tissue cells. Endothelial Cells Porous Interface With ACM Astrocytes No ACM LEFT: Co-Culture of endothelial cells (stained with CD31) and astrocytes (stained with GFAP) in the SynBBB model highlighting communication across the porous interface. RIGHT: Real-time visualization of fluorescently labeled small molecule permeation across the BBB. Flow and Astrocyte Conditioned Media (ACM) synergistically control tight junction formation.

SynRAM 3D Inflammation Model SynRAM TM allows the study of the entire inflammation pathway in a realistic and dynamic environment. By a histological slice of co-cultured tissue and/ or tumor cells with a lumen of endothelial cells, SynRAM delivers a physiologically realistic model and enables real-time tracking of rolling, adhesion and migration processes. SynRAM has been successfully validated against in vivo studies showing excellent correlation with rolling velocities, adhesion patterns and migratory processes. Physiological flow within a microvascular environment In vivo like vascular morphology with fully formed lumen Co-culture capability for cell-cell interactions Quantitative real-time rolling, adhesion, and migration data from a single experiment SynRAM enables real-time assessment of cellular interactions comprising of rolling, adhesion and migration through multiple cellular layers in a single experiment with close correlation to in vivo results. The SynRAM model reproduces inflammation responses observed in vivo Real-time visualization of leukocyte rolling, adhesion and migration across an inflamed endothelium in the SynRAM 3D model. Leukocyte rolling velocities are similar to those observed in vivo. Leukocyte adhesion pattern in SynRAM model matches leukocyte adhesion in vivo. Screening of inhibitors in SynRAM model. In the presence of inhibitor, migration drops significantly (by more than 75%) compared to control conditions. Simultaneously visualize rolling, adhesion and migration in a single experiment
